maybe one of you ran into the same problems. When I instantiate Print2FlashDoc, either with the Flex Component or the Flash CS3 Class via UIComponent, it throws an undefined error in stage set focus. It only happens when i close the print2FlashDoc and click on something else. But the weird thing is, it only happens if the first user interaction is opening the Print2FlashDoc. If i do something else it doesn't.

Also while in Flex Debugger it throws an undefined error, if I open it in a debug flash player it says stack overflow.
